Chrysanthemum plant named ‘Zanmuaval Purple’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmuaval Purple’ characterized by its medium sized blooms with dark purple ray florets and prolific branching; natural season flower date week 42; blooming for a period of five weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmuaval Purple’.

RELATED CULTIVARS

The new plant is a mutant obtained from the chrysanthemum plant ‘Zanmuaval’ (U.S. Plant Pat. No. 22,659).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmuaval Purple’. The new plant is a product of a breeding and selection program which had the objective of finding color mutants from existing parent plants. The new plant comprises a whole plant mutant of the chrysanthemum plant named ‘Zanmuaval’ Plants from the new cultivar ‘Zanmuaval Purple’ differ from plants of the parent in the color of the ray-florets. The ray-florets of the mutant plant are more dark purple than those of the parent plant.

The new cultivar was discovered as a color mutant in April 2010 by Wilhelmus Bernardus Blom in a controlled environment (greenhouse) in Rijsenhout, The Netherlands. The first act of asexual reproduction of ‘Zanmuaval Purple’ was accomplished when after planting of the mutant as a motherplant in May 2010, vegetative cuttings from this mutant were taken and propagated further in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of blooms of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands, under natural day length and temperature and planted in week 22 in 2011. The natural blooming date of this crop was October 15 (week 42). The average height of the plants was 30 cm. No growth retardants were used. No tests were done on disease or insects resistance or susceptibility. No tests were done on cold or drought resistance. This new variety produces medium sized blooms with dark purple ray florets blooming for a period of five weeks.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmuaval Purple’ is its parent plant ‘Zanmuaval’ (U.S. Plant Pat. No. 22,659).

The following is a description of the plant and characteristics that distinguish ‘Zanmuaval Purple’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is: The Royal Horticultural Society Colour chart, edition 2001.
